LUBRICATOR.

`SPECIFICATION forming part of Letters Patent No. 276,068, dated April17', 1883.

Application tiled February 13, 1383. (No model.) Y

To all whom it may concern:

Be it known that I, WILLIAM P. PHILLIPS, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented a cerv tain new anduseful Improvement in Lubricators, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specifi-cation, in explaining itsnature, in

Io Which- Figure 1 is a view, partly in section and partly in elevation,of a lnbricator having my improvements. Fig. 2 is a view in elevation,the lubrieator being turned from the position shown in Fig. l torepresent the sight feed, and having a portion of the water-column pipebroken out to show the construction beyond.

Referring to the drawings, A represents a cup, chamber, or reservoir; B,the standard supporting the same,and preferably east therewith, andhaving the screw-thread b, whereby it is attached to any desirable partof the boiler or engine. This standard or port B has the passage b',which is connected at its lower end with a steam passage or chamber.Leading from the standard is the pipe O,which has the passage c. Thispipe C connects with the vertical pipe D, and the passage cin said pipeC forms the communication between the steamchamber b in the standard Band the pipe D. This pipe D, by means of the cross-connection d, isattached to the cup or reservoir A, and the passage in said pipe iscontrolled by means of the valve d. This arrangement of the piping C Dforms a condensing apparatus, the steam gradually cooling in its passagethrough the pipe C, and the pipe D being filled or partially tilled withwater, which enters the chamber A therefrom as rapidly as the valve dpermits it. Extending from the upper portion of the chamber A, or fromthe neck c thereof', is the horizontal pipe c. This pipe, at its outerend, has a controlling-valve, e', which has adownwardly-projectingextension,e2. Between this extension and theupwardly-extending portion e3 of the cross-pipe e is the sight feed pipeor chamber E, which is secured in place between the extensions cz c3 inany desirable way. The passage in the pipe e4 opens into 5o the passageb' in the standard B, and there is a teat or nozzle, e5, in the sightfeed chamber E, which forms a continuation of the passage in thevalve-extension e2. The neck c has an opening through which lubricant isintroduced into the chamber A, which is closed by the screw plug or capc, and there is additionally a cock, c2, by which the cup may bedrained.

In operation the chamberA is filled with oil or other liquid lubricantof a similar nature. The steam enters the passage or chamber b 6othrough the passage o and condenses in the pipe I), and the watertherefrom enters the chamber A, raising the oil and causing it to dowout ot' the chamber through the pipe e, through the transparent chamberor, pipe E, into the passage b. Either the valve d or the Valve e', orboth, may be used for regulating the rate of feed. There is no valvebelow the nozzle or teat e5 in the sight feed chamber or tube, and theoil drops directly into the steam- 7a passage in the tube or chamber E,a cross-pipe, e4, connecting directly with the chamber or passage b.

The invention is an improvement upon that described in my pendingapplication filed November 20,18S2,and allowed January 9, 1883; and itvaries therefrom in respect to the location of the sight feed chamberand the variation in construction necessary for obtaining such change.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. In a lubricator, thecombination of the oil cup or reservoir A, the vertical standard 8 5 orpipe B, having the steam-passage l1', the steam-supply pipe andcondensing-tube connecting said passage with the oil cup or reservoir,substantially as indicated, the sight feed chamber E, connected with theoil-chamber 9ov and with the vertical pipe or standard B, as described,and the valves d c', or either et' them, all substantially as and forthe purposes set forth.

2. In a lubrieator, the combination of an 95 oil-reservoir and means forforcing oil therefrom, substantially as specified, a sight feed chamberarranged at one side of the oil-chamber, and connected at its top withthe top of the oil-chamber, and opening at its bottom roo into ahorizontal passage leading to a vertical oil-cond uctin g andsteam-supply pipe, a standard, B, and means for regulating the rate offeed ofthe oil through the sight feed chamber, whereby oil is fed fromthe reservoir into a Vtnesses: transparent chamber filled 0r partiallyfilled F.
